| 4. Designation by counties and municipalities. County |
| commissioners and municipal officers may designate public ways |
| other than those in subsection 3 and impose restrictions within |
| their respective jurisdictions similar to those made by the |
| Department of Transportation under subsection 3. Any vehicle |
| delivering home heating fuel and operating in accordance with a |
| permit issued by the Department of Transportation pursuant to |
| this section may travel over any county or town way without a |
| specific municipal or county permit. A municipality may impose |
| additional restrictions for home heating fuel delivery trucks to |
| operate on public ways within that municipality but may not |
| require a permit to operate according to those restrictions. |
| County commissioners and municipal officers may restrict vehicle |
| travel over such public ways based solely on gross registered |
| vehicle weight. |
